Who else wishes the 1D X and 5D III have iPad control/view?

I can use my Transformer Prime (wired) with my Canon DSLR's using the inexpensive DSLR Controller app. With this setup I can see the live view of the camera, adjust settings and shoot from the tablet. The images are transfrerred to the tablet for viewing.

I also have used an EyeFi SD card in an adapter with my Canon bodies to send images wirelessly to the tablet.
Your real problem is Apple and their closed system.
